ACAR-AXLE Box.

SPECIFICATION forming part of Letters Patent No. 239,702, dated Aprilv 5, 1881. Application tiled January 29, 1881. (No model.)

To all whom it may concern:

Beit known that I, SUMNER A. BEMIS, of Springfield, in the county of Hampden Aand State of Massachusetts, have invented a new and useful Improved Car-Axle-Box, (which has not been patented to any person in any foreign country with my knowledge and consent,) of

` axle box and its housing as is necessary to show the spring-socket and the springin place therein. Fig. II is a vertical transverse sectionthrough the axle-box and axle, and showing a front view of the housing. Fig. III is a plan view with a portion of the wheel and the housing broken away, and in section to show the sleeves on the housing and on the wheel and the washer connected therewith. Fig. IV is a side view of the spring. Fig. V is an end view of the same. Fig. VI is a front view of the washer, and Fig. VII is an edge view of the same.

In the drawings, C represents a car-axle; B, the car-wheel; E, the axle-box, and A the housing at the inner en-d of the box, on the iuner part of which housing is made a tubular sleeve, 2, tapered on its periphery, as shown clearly in Fig. III. That part of the housing nearest the car-wheel is filled with wood blocking or other Suitable material, 8, with a circular space between the blocking 8 and the sleeve 2, to receive the sleeve or liange l, cast on the outer face of the wheel. A washer, 3, is placed on the Sleeve 2, the'hole through the washer being a little smaller than the largest part ot' said sleeve 2, and when the axlebear ing is in its proper position inthe axle-box the end of the sleeve or flange l on the wheel impin ges against the washer, and. tends to crowd the latter farther upon the sleeve 2, and when in this position, as there is always contact between the `end ot the iiange on the wheel and the side of the washer, and also contact between the inner rim of the washer and the outer surface of the sleeve 2 on the housing, of course the dust cannot get past the washer into the axle-box.

On the inner side of the exterior part of the housing A-that is to say, on the-side opposite the wheel and next the pedestal D-I cast a box or socket, consisting of three walls or flanges, 5, projecting outward from the' side of the housing, but with no wall or iange at the top 5 and these walls or dan ges are made of a dovetail form on theinside, orinclined,as shown clearly in Fig. III, and into this socketIinsert from the top a rubber sprin g, 6, of nearly the same length as the inside ofthe socket 5, and having its sides inclined to correspond with the interior of the side walls of the socket, so that the spring will betretained in its place in said socket. A metallic piece, 7, may be riveted or otherwise secured to the exposed front side of the spring 6, to protect its front side from abrasion by contact with the pedestal. Figs. Il and III show one of the sockets with thelspring 6 in place therein and the other.

socket empty. V

Vhen the car is in use, as it sways from one side to the other, the pedestal comes in contact with the spring 6, or the metal piece secured thereto, and the rubber is compressed, and the side motion of the car is thereby made much more easy.

When the springs become worn or useless from long-continued use it is only necessary to remove the worn or useless spring by drawing it upward and out ot' the socket and inserting a new one, and as the springs and sockets require no particular finish, they are very cheap and are very durable.

It isevident that it the socket to hold the rubber spring be made on the vertical side of the pedestal next the vertical side ofthe housing, so that in use, in the swaying movement ofthe car from one side to the other, the housing should strike against the rubber spring, instead of the pedestal striking against it, the result would be the same in easing the Side motion of the car, and the invention would not be departed from in the least, so long as the sprin g was held in position between the pedestal and the housing, to be compressed by them.

.It is also evident that as the dovetail shape is given to the walls of the socket to hold the IOO spring securely in place without the aid ot other devices, an in wardly-projecting lan ge on the outer portion of the walls of the socket, for either the whole or a portion of its length, would operate in precisely the same manner in holding the spring in place.

Having thus described my invention, what I claim as new is- 1. The combination, in a car-axle box, of the car-wheel provided with a ange projecting out from the side ofthe wheel and around the axle, a tapered sleeve ou lthe box or its housing proj ectinginto the said ange on the wheel and surrounding the axle, and awasher placed upon said tapered sleeve on thebox,and there confined by contact with the end of the ange on the wheel, substantially as described.

2. The combination, with a socket made on the vertical` side of the housing or of the adjacent side oi' the pedestal of a car-axle box, ot' 2o
